We're selling Dacron sail sets which include a Main and Jib with all the normal bells-and-whistles: leech-lines, tell-tales, one-hand stainless hanks, reef points, sail bags, great construction, etc! Shipping costs vary (even in the US now) and will be determined when you order. It is possible to order custom sets of sails in Tanbark or Cream/Natural, and even other colors. Tanbark or Natural is 15% over the standard prices and we can check on the cost of other colors for you as you require.
Back when we started using tarp sails, we had a few sailcars and decided to find out how much better the "real" Dacron sails were. A sailcar like our Vector is a great test, as they really wring out the bugs in a hurry! We found (after quite a bit of swapping around in different configurations) that the Dacron had a bit of an edge in lighter airs, but the tarps were much better as the wind picked up! I won't presume to figure out why, but over the years we have not felt the need to go with "real" sails very often. Our Weekender (with a nice set of Dacron sails) has been beaten by a Weekender with tarp sails, although that was likely weight differences in the two boats and skill!
The Dacron sails would be a much better choice if you were going on an extended cruise, but these boats a really more for short-term jaunts. The tarp sails really do work fine! If you want the longevity of Dacron, and the cozy feeling of knowing your sails are no longer something to think about, then you have that option. We like having the Dacron sails on our boats now, but never felt that the tarp sails were a disadvantage.
